    Biodentine's strong sealing ability is crucial in endodontics to prevent bacterial invasion and promote healing. It offers a reliable solution for many pulp- and root-related procedures.

    For example, during an apexification procedure on a tooth with an open apex, Biodentine serves to form a barrier that facilitates the natural closure of the root apex over time, promoting successful healing.

    Endodontics is a specialized field of dentistry that focuses on the study and treatment of the dental pulp and tissues surrounding the roots of a tooth.

    Biodentine Direct Pulp Capping

    Direct pulp capping involves placing a material over an exposed pulp in an effort to maintain pulp vitality. Biodentine, with its bioactive properties, is a material that is often chosen for this procedure due to its ability to form a dentine-like structure and promote healing.

    Procedure for Biodentine Direct Pulp Capping

    Carrying out a direct pulp capping procedure with Biodentine requires precision and understanding of both the material and the affected tooth. Here's a step-by-step guide on how it is performed:

    • Diagnosis and Assessment: First, assess the condition of the pulp to ensure that the tooth is a suitable candidate for pulp capping.
    • Anesthesia and Isolation: Administer local anesthesia to the patient and isolate the tooth using a rubber dam to maintain a dry field.
    • Cavity Preparation: Remove all decayed tooth material carefully while exposing the pulp minimally.
    • Hemostasis: Achieve hemostasis, typically with a sterile saline solution, before placing Biodentine.
    • Placement of Biodentine: Mix and apply Biodentine over the exposed pulp using a spatula, ensuring it's placed directly over the pulp exposure site.
    • Setting and Temporary Restoration: Allow Biodentine to set. Cover it with a protective temporary restoration to ensure the area is shielded from further irritants.
    • Assessment of Treatment: Follow up with the patient to monitor healing and determine if further treatment is necessary.
    Using Biodentine in this procedure offers the dual benefit of sealing the exposure site and stimulating natural healing processes in the pulp.

    Always ensure the field is completely dry before placing Biodentine, as excessive moisture can interfere with setting.

    Direct pulp capping is a dental procedure where a material is applied directly on the pulp tissue after a mechanical exposure to maintain vitality and promote healing.
